[0002] The low-speed flow-pushing series of mixers are mainly suitable for aeration tanks and anaerobic tanks in industrial and urban sewage treatment plants. They produce strong water flow with low tangential flow, which can be used for water circulation in the pool and to create water flow in the nitrification, denitrification and phosphorus removal stages. The existing submersible low-speed flow-pushing device can basically meet the daily use needs, but there are still some shortcomings that need to be improved.

When the flowmaker is damaged, it is inconvenient for people to disassemble and assemble the flowmaker because the flowmaker is inside the water, which affects the efficiency of maintenance and reduces its practicality.
